AUTOMATIC CHALK-HOLDER FOR BlLLlARD-TABLES.

SPECIFICATION formingpartof Letters Patent No. 294,516, dated March 4;, 1884.

Application filed February 7, 1884- (No model.)

' tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference'marked thereon, which form a part of this specification.

My invention has relation to chalk-holding devices for billiard-tables; and the object of the invention is to provide a holder for the chalk, whereby it is secured to the table in such a manner-as to allow of its free manipulation, and after use toautomatically return to its place in the chalk-cup; and to these ends the novelty consists in a the cube of chalk and a rubber bumper or cushion to prevent injury to the chalk, combined with a cord and spiral spring, all of which will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying'drawings similar letters of reference indicate the same parts of the invention.

Figure l is a perspective view of the clamp; Fig. 2, a similar view of the cube of chalk, the clamp with the cord attached thereto, and the rubber bumper, the parts being separated, so as to more clearly show their construction. Fig. 3 is a view of one end of a billiard-table, showing my device applied thereto, and the dotted lines show the chalk-holder removed from the cup to allow its use. Fig. 4is a sectional elevation of the device in position and ready for use.

A is a square clamp of a size corresponding to the ordinary chalk-cube.

B is a bolt, one end of which passes through the side a of the clamp A, and having that end upset, so as to form a head, 11. The bolt B then extends across the clamp A, through the side a, and thence through the end of, where it is screw-threaded to receive the thumb-nut O. The portion 12 of the bolt B is bent-at'a-n angle of about one hundred and clamp for holding operation of chalking thirty-five degrees-to the body of the bolt, so that by this inclined portion 2), as the nut Cis screwed up, the side a will be pressed toward the opposite side a, and at the same time the side a will be compressed against the side a and it will thus be seen that all four sides of the chalk-cube D will be firmly clamped and rigidly held in place by simply tightening the center of the bolt B. This cord extends down.

ward through a hole in the cup G into the tube I, and its end is secured to a spiral spring, K, the lower end of which is made fast to the bottom 11 of the tube. The chalk and rubber being secured in the clamp, as shown in Fig. 4:, the chalk is grasped by the finger and thumb and raised out of the cup to be used in the the one, as shown in dotted lines in Fig. simply releases it, and the spring K restores it to its original position in the cup, the rubber forming a cushion and preventing the chalk breaking. A

In order to apply my device to tables in use, it is only necessary to bore a small hole through the bottom of the chalk-cup and attach the tube to the table in any suitable man ner, underneath said cup.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is-

1. The clamp A, provided with the bolt B, having nut O, as and for the purpose set forth.

2. The clamp A, having bolt B, with angular bend b and nut O, as set fort v 3. The combination, with the clamp A, chalk-cube D, and cord H, of the rubber bumper E, as and for the purpose set forth.

5. The clamp A and bolt B, bumper E, and

cord H, in combination with the cup G, tube 3. After use, the operator I, and spring K, as and for the purpose set In testimony whereof Iaffix my signaturein forth. presence of two witnesses.
